The equation of the line of best fit is y = -0.368x + 18.483. based on the line of best fit, approximately how many inches of snow fall during the month of january when the average temperature is 2°f? a. 17.7 b. 19.2 c. 23.9 d. 44.8

17.7 inches.

Step-by-step explanation:

The equation of the line of best fit is y = - 0.368x + 18.483 (1)

Based on the line of best fit, we have to approximate how many inches of snowfall during the month of January when the average temperature is 2°F.

So, here, x = 2 and we have to calculate y using the equation (1).

So, y = - 0.368 × 2 + 18.483 = 17.747 ≈ 17.7 inches. (Answer)

d

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
